154 A MANUAL FOB NORTHERN WOODSMEN 



TABLE III 



Same logs but grouped according to mid diameter outside 

 bark. 



The figures of the above tables were closely confirmed, 

 except in the smallest sizes of logs, by similar figures ob- 

 tained by the U. S. Forest Service for the Forest Commis- 

 sion of New Hampshire. The saws in this latter test cut 

 J-inch kerf; 60 per cent of the product was round-edged 

 stuff, the balance being squared ; 70 per cent of the lumbei 

 was cut 1 inch thick, the balance 2^ and measured as 2 

 inches. In the sizes under 8 inches the Massachusetts 

 mills cut somewhat closer.
